Which group of letters will come next in the given series?
AIH, DJK, EKL, HLO, ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → IMP
In a series of letter groups, each place in the group follows its own rule, so the first, middle and last letters are checked separately using their places in the alphabet.
First letters A (1), D (4), E (5), H (8): steps \(+3,\ +1,\ +3\) in turn, so the next step is \(+1\): \(8+1=9\), which is I
Middle letters I, J, K, L: the next letter each time, so next is M
Last letters H (8), K (11), L (12), O (15): steps \(+3,\ +1,\ +3\) in turn, so the next step is \(+1\): \(15+1=16\), which is P
So the next group is IMP.
